Book excerpt: The Nigerian telecommunications industry has continued to grow in a phenomenal manner following market liberalization reforms that commenced in the 1990s. As of 2017, the telecommunications industry was one of the fastest-growing economic sectors in Nigeria and the fourth largest contributor to the country’s Gross Domestic Product. The telecommunications industry, however, remains a highly technical and naturally dynamic industry that has not been a usual area for legal research in developing countries such as Nigeria. This book bridges that gap in knowledge by providing an analysis of the legal and policy instruments that regulate the industry. It comprises eleven chapters that discuss the historical evolution of telecommunications and its regulation; the development of the Nigerian telecommunications industry from 1886 to 2017; the legal basis for the regulation of the industry; the licensing and duties of service providers; the regulation of network infrastructure; the protection of consumers; the regulation of competition, interconnection, universal access, and environmental protection; and the resolution of industry disputes. This book will be useful to policy makers, legislators, regulators, lawyers, law students, investors, operators, and consumers, as well as any person interested in the Nigerian telecommunications industry.
